ya especially if u have an upgraded fuel pump...i have a walbro pump in my turbo d-series hatch and when u turn the key u can hear the pump humming....it could be the distributor....i had a problem which seemed like a alternator problem but it turned out that autosolution(may that shop burn in hell) put the wrong damn one on my car....id check ur timing and get a voltmeter and test the charge coming off ur alternator...if its below 12 then u might wanna think about getting a new one
